beginShape()

Begin an extruded path built from vertex() points.

The first vertex() after beginShape() positions the nozzle at the start of the path; every following vertex() extrudes to the next point. mode chooses how the first move is made i.e. how the nozzle reaches the path start:

• TRAVEL: retract, z-hop, and re-prime (the default; like travelTo())
• RETRACT: retract and re-prime, no z-hop (like retractTo())
• MOVE: a plain move with no retraction or z-hop (like moveTo())
• EXTRUDE: extrude from the current position to the first point (like extrudeTo())

Call endShape() to finish, or endShape(CLOSE) to extrude back to the first vertex. The functionality follows beginShape() / vertex() / endShape() in p5.js.
